BLOCK-COPOLYMER HYDRIDE HAVING ACID ANHYDRIDE GROUP AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2017/135177

Kind Code:

A1

Abstract:

The present invention pertains to a laminated glass obtained by: interposing, between glass plates, a resin sheet comprising a resin composition obtained by blending 100 parts by weight of a specific modified block-copolymer hydride having an introduced acid anhydride group, and a total of 0.001-2.0 parts by weight of a near-infrared absorbing dye and/or fine metal oxide particles having the function of blocking infrared light, to obtain a laminate; and integrally bonding the laminate including the glass plates and the resin sheet. The present invention provides: a novel block-copolymer hydride having an acid anhydride group; a resin composition which contains the block-copolymer hydride, and is suitable as a material for the formation of a middle film for a laminated glass that has an excellent heat shield function and excellent moisture resistance and durability; a resin sheet comprising the resin composition; and a laminated glass obtained by interposing the resin sheet between glass plates via an adhesive to obtain a laminate, and integrally bonding the laminate including the glass plates and the resin sheet.
